<h2>Minor Head Injury (Simulated) Data</h2>

<h3>Description</h3>

<p>The <code>headInjury</code> data frame has 3121 rows and 11 columns.
The data were simulated according to a simple logistic
regression model to match roughly the clinical characteristics
of a sample of individuals who suffered minor head injuries.
